Bartley's sister Megan, a healthy, active, 18-year-old, was taken down by deep vein thrombosis and pulmonary embolism in February, and continues to battle the effects from being stricken. Bartley says approximately 14,000 Coloradans are diagnosed with blood clots each year, with nearly 5,000 of them ending in death.

Bartley helps spread the word about blood clot awareness through a campaign called The Clot Must Be Fought. The mini-ping-pong marathon is part of that effort.
